Standardization of optimum dose and time of nitrogen application to tissue cultured Grand Naine banana

A field experiment was conducted to find out the need of nitrogen during vegetative and reproductive phase and to standardize optimum dose and time of nitrogen application to tissue cultured Grand Naine banana under drip irrigation on medium black soil. Application of nitrogen at 250 g/plant i.e. 200 g/plant N in four equal splits at 30, 75, 120 and 165 days after planting in vegetative phase and remaining 50 g/plant N in three equal splits at 210, 255 and 300 days after planting in reproductive phase found beneficial and economical in terms of banana yield and monetary returns. Nutrient uptake by crop was highest in the treatment where nitrogen was applied at 250 g/plant.
